Overview
The CD74AC05M is a hex inverter integrated circuit produced by Texas Instruments. This device is part of the AC family of logic gates and features six independent inverters. Each inverter performs the Boolean function Y = A, where Y is the output and A is the input. The CD74AC05M is known for its wide operating voltage range of 1.5V to 5.5V and its balanced noise immunity at 30% of the supply voltage. This makes it suitable for a variety of digital logic applications requiring high reliability and low power consumption.
